How do I replace the player with a rigid body object? BGE
when you press space. use python to add a invisible ball.

parent the snails physics object to the ball no collision.

the snail,should be

Cube (physics,bound)



armature parented to cube



skin parented to armature



and the ball should be a rigid body,

invisible, sphere physics, bound

your going to want to use python and a timer to do it

let me know if you need more help.
